PISCES (Feb. 19-March 20)

Here's one way to reduce global warming: inject huge amounts of sulfur into the atmosphere. So says Professor Tim Flannery, an Australian sustainability activist. What's the best way to accomplish that? Add sulfur to jet fuel. The atmosphere would then repel a portion of the sun's rays, leading to an effect called "solar dimming."

Oh, by the way: As a side effect, the planet's sky would probably turn yellow -- a rather extreme shift, Flannery acknowledges, but necessary if we want to save the environment. Are you contemplating an equally drastic step in your own personal sphere, Pisces? Before you decide to go in that direction, why not try a series of smaller, incremental actions with less dramatic consequences?
